The chemical name of the baking soda is:
Correct answer: B. Sodium bicarbonate
- A. Sodium carbonate
- B. Sodium bicarbonate
- C. Sodium chloride
- D. Sodium hydroxide
- E. Both B and C
Explanation
The correct answer is Sodium bicarbonate. Sodium bicarbonate, also known as baking soda, is a chemical compound used primarily as a leavening agent in baking. It reacts with acids to produce carbon dioxide gas, which causes dough to rise. The other options are incorrect: sodium carbonate is used in cleaning and water softening, sodium chloride is table salt, and sodium hydroxide is a caustic substance used in cleaning and manufacturing.
